Large Swath of Dead Mangroves, but Why? SLR/IRL

Google Earth image showing dead mangroves, 9-11-18

Recently a gigantic swath of dead mangroves, east of the Indian River Lagoon on Hutchinson Island in Jensen Beach was brought to my attention. About a year ago, I had noticed the dead forest of trees; however, with my full attention on toxic-algae, water-quality, or lack thereof, I had put this graveyard of walking trees out of my mind. Until I got a phone call a couple of days ago…

My contact, as many others, proposes fundamental changes, such as culverts or another small inlet between the barrier island and the IRL to allow more flushing and increase salinity, pointed out that the primary reason the mangrove forest died, post Hurricane Irma, was too much fresh water. He also noted that the toxic-algae, as bad as it is, is not the worst killer for our St Lucie River. The worst killer is an old enemy: too much fresh water from Lake Okeechobee and area canals. The fluorescent toxic algae has just “put a face” on the carrier, the real enemy, too much fresh water.

The St Lucie is an estuary (https://oceanservice.noaa.gov/facts/estuary.html) and needs salt water to exist, also the microcystin toxin cannot survive in a brackish system. The constant discharges,  from Lake Okeechobee especially,  continually push fresh water through a once brackish system, poisoning it, and toxic algae is along for the ride…

I found this message a powerful tool in visualizing what has happened to our St Lucie River. The dead mangroves are indeed a metaphor for the entire St Lucie River/Indian River Lagoon system: our lush seagrass beds have died and the water quality is terrible, leaving little or no wildlife.

We must remember, below our waters, too much fresh water has caused a dead forest too.

Below, I am including Martin County’s response to my inquiry about the dead mangrove forest as a matter of public interest and education.

Jacqui,

This loss of mangroves at the JBI site prompted a serious investigation by the Mosquito Control and Environmental Resources Divisions. Given the large-scale mortality event, testing was conducted to rule out site contamination. Water quality testing was also conducted to determine dissolved oxygen, pH, salinity, and hydrogen sulfide levels. The Florida Department of Environmental Protection, St. Johns Water Management District, Smithsonian, a local mangrove arborist and Ecological Associates Inc. were all consulted regarding concerns over the mangroves. The majority opinion was that heavy late season rain and high water levels were the primary cause of the mangrove mortality with hurricane stress and suspended solids associated with storm surge as secondary causes. Additionally, lack of species and age structure diversity contributed to the loss, more diverse communities are associated with greater resiliency. Areas in close proximity to the JBI show evidence of mortality caused by ‘ponding’ in which high freshwater levels result in the loss of vegetation.

Recommendations going forward are to improve hydrological connectivity through the installation of additional culverts, clear out channel sedimentation, and install spillways. These actions will improve water quality by allowing for more exchange with the IRL and also increase the discharge capacity of the south cell to prevent high water levels associated with heavy rain and storm surge. In order to accomplish these actions, a capital improvement plan for the site was tentatively approved by the board on April 10th, 2018. Additional funding opportunities will be sought for site improvements and the board granted permission on July 24th, 2018 for staff to pursue State Wildlife Grant funding from the Florida Fish and Wildlife Commission.

While funding opportunities are being sought, in-house activities have been pursued. Specifically, staff gauges have been installed to monitor natural tide conditions to allow for careful water level monitoring. The Project Engineer from Field Operations has put together a conceptual plan. A failed culvert is in the process of being replaced. Blockages along the perimeter have been identified and several have been cleared. Transects are being put in for vegetative monitoring. New growth can be seen within the JBI site, however, this is primarily restricted to the areas in closest proximity to the IRL. Culverts are currently opened to allow for natural recruitment and mosquito control is being accomplished through alternative means to allow the area to reseed.

Let me know if you would like to meet to discuss this.

Comment from my mother w/historic photo” “My goodness. I am glad the county is correcting the problem that seems to me, to be that there was no longer tidal action in the mosquito ditches. When I interviewed pioneers like the Pitchfords, who I believe once owned this land, they said originally there were no mangroves. The government dug mosquito ditches connected to the lagoon by culverts causing the mangroves to flourish. Then laws protecting mangroves, made it impossible to develop the property. I guess there were ways to get around this because Sailfish Point and Indian River Plantation were criss-crossed with mosquito ditches and covered with mangroves. I have many photographs I would like to share but I do not know how to add them to this.” Sandy Thurlow (photo Aurthur Ruhnke 1956, Thurlow Collection)

What is Deep Well Injection? What are Estuary Protection Wells? SLR/IRL

Image courtesy of FDEP – Locations, Deep Injection Wells, South Florida 2018

“Deep Well Injection” is a term uncommon at most dinner tables. However, it is becoming more so because the South Florida Water Management District has interest in creating deep well injection “Estuary Protection Wells” around Lake Okeechobee. These wells would “lessen discharges from Lake Okeechobee to the St Lucie and Caloosahatchee Estuaries,” hence the name. Of course there is a spin factor here as Estuary Protection Wells sounds better than Deep Well Injection that has a negative connotation, in spite of its popularity in the state of Florida.

So what is deep well injection?

In the 1930s the petroleum industry pioneered the technology, injection of liquids (produced brine from their processing) into underground formations. Over time, this procedure was adapted to many other forms of waste byproduct. According to the U.S. Environmental  Protection Agency’s website, as the popularity of injection wells expanded,  the Federal Government set protections. In 1974, Congress passed the Safe Drinking Water Act,  requiring the U.S. Environmental Protection Agency to develop regulatory requirements to control underground injection. These regulations are called underground injection control rules (UIC)  and continue to regulate safety of drinking water throughout the United States today. (EPA: https://pubs.usgs.gov/of/1988/0477/report.pdf)

EPA website Class I DWI

For the Environmental Protection Agency deep injection wells fall into six categories:

Class I industrial and municipal waste disposal wells 
Class II oil and gas related injection wells
Class III solution mining wells
Class IV shallow hazardous and radioactive waste injection wells
Class V wells that inject non-hazardous fluids into or above underground sources of drinking water
Class VI geologic sequestration wells
(https://www.epa.gov/uic/class-i-industrial-and-municipal-waste-disposal-wells)

Interestingly enough, again, according to EPA’s website “approximately 30 percent of Class I wells in the U.S. are municipal waste disposal wells and these wells are located exclusively in Florida. It must have something to do with Florida’s geology, or the laziness of our state to want to clean up the water. (Sorry, I could not resist.)

You can see from the 2013 map below exactly where these wells are located; a number of them are located in Martin and St Lucie Counties. Partially treated grey-water or waste water is sent thousands of feet below the Earth’s surface into a “boulder zone” where there is space to hold it and it is “separated” by geological barriers from aquifers and surface waters.  Generally it is believed this boulder zone is connected or has an outfall many miles out in the ocean and would leak ever so slowly, if it did at all, and  in a time frame so slow it would be incomprehensible to humans…. Hmmm? (https://wasteadvantagemag.com/wastewater-deep-injection-wells-for-wastewater-disposal-industries-tap-a-unique-resource/)

So if the SFWMD is able to implement Deep Well Injection, it would not be unknown technology, it would be nothing new, nothing Florida isn’t already doing ~taking the easy way out…not cleaning the water on land…

Is it laziness, just more of the same, or something to consider as the Comprehensive Everglades Restoration Plan (CERP) is painstakingly implemented as mentioned in the **UF Water Institute Report of 2015?

Doing the right thing is not easy, however, in the meanwhile the estuaries could totally die. Purchasing the land, insuring funding from Congress every two years, dealing with stakeholders, enduring the slow-pace of the Army Corp of Engineer’s approval process, designing Storm Water Treatment areas that don’t make anybody mad, planting the new vegetation to clean the polluted water running from industrial farms and fewer municipalities into Lake Okeechobee without wrecking the environment for another animal like a poor gopher turtle, takes a lot more time and effort…

In fact, it might be decades before things are in place…

And this is why the South Florida Water Management is considering the wells. I will not say that I agree, but as I sit here surrounded by a dead, toxic-algae filled St Lucie Estuary, I  will admit, I empathize.

The “Michigan J. Frog” Blue-Green Algae of the IRL

Harborage Marina here and below, an area the algae is “always present” looks clear on 8-19-18. JTL

When I was I kid, I loved to watch Looney Tunes. For some reason, my favorite cartoon was the story of “Michigan J. Frog,” the singing frog that would stop singing when its “owner” would take it out of the box to perform.

Although our St Lucie cyanobacteria issues are no performing frog, and are anything but funny, sometimes I do feel like I am in Looney Tunes. And most certainly, the singing frog analogy stands.

Recently, when some big-names came to visit our area to “see” the algae, I must admit, when it wasn’t, I wanted it to be there. This happened with famed conservation photographer Max Stone, and the next day with gubernatorial candidate Ron DeSantis’ ToxicTour with Congressman Brian Mast.

In both cases, just a day apart, we would be staring at an area famous for caked, stinking algae, photographed thousands of times, and the area would look “clean,” completely devoid of the thick green-blue mats. In a desperate attempt for credibility, I’d be showing Max Stone or Congressman DeSantis pictures on my phone displaying how the algae looked “just last week”….”just yesterday!” “See those grey lines on the seawall, they were blue!”

They believed me of course, they’d seen the national news, but it would have been so much more convincing if I had been able to show them the fierce algae face to face! AGGG!

But that’s not my decision. The algae comes and goes. And most important, thick or thin, it is always there. The particulate algae is just as bad as the mats, just not as emotionally charged.

And of course, the moment these big names left, just the next day in fact, the algae started coming back ~like these photos shared this morning by Mary Radabaugh from famed Central Marine in Rio.

Maddening! Isn’t it?

8-23-18 Mary Radabaugh shares photos here and below of cyanobacteria blue green algae” back in Marina. It was not visible like this when I visited just days before.

I guess the lesson is, and what we must know, and be able to explain, is that the algae, like the character Michigan J. Frog, during times when Lake Okeechobee is being discharged, the algae whether performing or not, is always there in the box/in the river.  Only the cyanobacteria/blue green algae will decide if and when it will sing…

Not so visible particulate cyanobacteria (blue-green algae) in the SLR, August 2018. JTL

And it probably won’t when you want it to, and it probably will when you wish it would not…it is a living creature with a mind of its own in tune with temperature and nutrients (food) not thinking of people at all.

In closing, take Bathtub Beach yesterday for a final example, now closed due to cyanobacteria. The same thing! I went to visit after hearing the beach had been closed, but by the time I got there the tide and winds had pushed most of the cyanobacteria out to sea. But it was still there, just quiet. Looking closely, the particulate clumps were gathered at the shoreline waiting to perform. Be certain, the frog, one day, of its own accord, will sing.

John Moran’s “Florida’s Summer of Slime: Stuart and Lake Okeechobee”

It’s an honor to present:

“Florida’s Summer of Slime: Stuart and Lake Okeechobee,” photo essay by John Moran, August 2018

I reported last month on the plight of the Caloosahatchee River and its befouled waters flowing from Lake Okeechobee; delivering slime to waterfront neighborhoods in Fort Myers and Cape Coral along the way to the Gulf Islands of Southwest Florida.

Next up on our Summer of Slime photo tour is a visit to Stuart and Lake O…Stuart and environs is a glistening jewel born of water. It may well top the list of Florida cities in shoreline per capita. There’s simply water everywhere. Two forks of the St. Lucie River, the Indian River Lagoon, canals and peninsulas and islands, and the Atlantic Ocean beyond. Stuart is pictured above; below is neighboring Hutchinson Island.

But it wasn’t Stuart’s reputation for abundant clean water that drew me south from Gainesville with my cameras. In effect, I’ve become a traveling crime scene photographer—and slime is the crime. A devastating outbreak of toxic algae has once again hit the St. Lucie River and the Treasure Coast, fueled by the polluted waters of Lake Okeechobee and the Kissimmee River basin to the north. Damaging headlines trumpet the story to the nation and the world and Governor Scott has declared a state of emergency. It’s déjà vu all over again.

My hosts in Stuart were water blogger Jacqui Thurlow-Lippisch and her husband, Ed Lippisch.

Ed took me up for a photo flight in his Piper Cub so I could get the big picture.

Seen from a small plane at 500 feet, Florida is a beautiful place.

Here’s Lake Okeechobee and the western terminus of the St. Lucie C-44 Canal. Administered by the U.S. Army Corps of Engineers, the Port Mayaca Lock and Dam has the capacity to discharge 14,800 cubic feet of water per second downstream to Stuart and the St. Lucie River Estuary, 26 miles away.

Sugar industry representatives say the water coming out of Lake Okeechobee is not the problem and that the algae outbreak in Stuart is primarily caused by Stuart’s own septic tanks and urban stormwater. This claim is contradicted by the extensive algae mats seen along the C-44 Canal between the Port Mayaca and St. Lucie Locks, well upstream from Stuart.

Lake Okeechobee historically drained south to Florida Bay, not east and west to the Atlantic and Gulf. The C-44 canal was built in 1916 to divert floodwaters to the coast.

A view of the St. Lucie Lock and Dam, several miles southwest of Stuart. On the day of my photo flight in late July, the dam gates were closed, visibly holding back algae from flowing downstream. Look closely and you can see what some people call The Seven Gates of Hell.

The St. Lucie Lock and Dam are an integral part of South Florida’s complex web of water management structures, born of an age when the Everglades was reviled as a watery wasteland and America was driven to drain it.

Below the St. Lucie Lock and Dam, in Palm City and Stuart, you can still find waterfront homes untouched by the algae bloom. But that’s no consolation for the thousands of Martin County residents whose lives are in upheaval once again this summer. The familiar pattern of algae outbreaks is fueled by fertilizer, manure and urban sources of nutrient pollution, including septic tanks.

All of this is compounded by denial and neglect by elected officials and agencies to whom we entrust the important work of environmental protection and public health.

Jacqui Thurlow-Lippisch took me on a driving tour of the C-44 Canal from Stuart to enormous Lake O, which is more like a stormwater treatment pond than a biologically healthy lake. “There are toxic algae blooms across the globe, but only one place where the government dumps it on you: Florida,” she says.

It’s not just the algae from Lake Okeechobee causing headaches along Florida’s east coast; the sheer volume of freshwater discharges is an environmental pollutant that overwhelms the estuary.

The Lake O gunk visible in the satellite view, above, is shown in the detail photo below.

Fishermen are still drawn to Port Mayaca. On the day we visited, I counted nine.

Dinner in hand (speckled perch), Felix Gui, Jr. has been fishing Lake O for 30 years. “The algae doesn’t affect the fish,” he says. “They eat the same, algae or no algae, and I haven’t gotten sick.” Experts have warned against eating fish exposed to the algae.

A Martin County Health Department sign at Port Mayaca warns against contact with the water but I saw no messaging about whether fish caught in these waters is safe to eat.

Enroute home to Stuart, Jacqui and I stopped at deserted Timer Powers Park on the St. Lucie Canal in Indiantown.

At the St. Lucie Lock, a surreal scene of impaired water, above, and a vortex of slime, below, waiting to be flushed downstream.

A pair of jet-skiers signaled for the lock to be opened, and another pulse of algae-laden water is released towards Stuart and the coast.

Wouldn’t want to anyway, thanks.

Further downstream, the algae spreads…

Nearing the coast, Rio Nature Park and the neighboring Central Marine in Stuart are slimed again. This was the epicenter of the infamous Treasure Coast algae outbreak of 2016.

Reporter Tyler Treadway of TCPalm gathered a sample of the polluted water from a canal behind the offices of Florida Sportsman magazine in Stuart.

Staff complaints of headaches, nausea and dizziness prompted Florida Sportsman publisher Blair Wickstrom to temporarily close the office in late July. “It smells like death,” he said.

The Shepard Park boat ramp parking lot in Stuart was nearly empty on the day we visited.

A man on a mission, Mike Knepper, above and below, posts videos on his Youtube channel documenting the degradation of natural Florida.

“It’s totally unacceptable to me what we’re doing to this planet because we’re very rapidly destroying it,” Knepper says. “My children and grandchildren will be paying the price for all the bad decisions we’re making today. I want to be able to look them in the face and say, ‘I tried to make a difference.’”

Dead-end canals along the St. Lucie River with their limited water exchange have been hardest hit by the toxic blue-green algae, which scientists refer to as cyanobacteria.

A growing body of medical research links exposure to cyanobacteria with neurodegenerative diseases including Parkinson’s, ALS and Alzheimer’s. Google it.

Meanwhile, we’re getting conflicting messages from officialdom. Martin County has erected signs warning against contact with the water but the Florida Dept. of Health website, under the heading How to Keep Your Family Safe While Enjoying Florida’s Water Ways, has this to say: “Cyanobacteria/ blue-green algae…are naturally occurring in Florida’s environment and are also found all over the world. They are part of a healthy ecosystem and help support a wide variety of aquatic life.” (http://www.floridahealth.gov/environmental-health/aquatic-toxins/cyanobacteria.html) In other words, Lighten up, Florida. This is just nature being natural.

An open question remains: What will become of the value of the Florida brand when the world fully sees what we have done to our waters?

Even in disaster, strange beauty emerges.

Greg Fedele has lived in his water-front home since 1991. He grieves for his loss. “I have three kids who can’t enjoy the waterways of Martin County like I did growing up.”

The sign at Ocean Blue Yacht Sales in Stuart echoes a wide swath of community sentiment. Asked to describe in a word how the algae outbreak has impacted his business, president Bryan Boyd replied, “Horrible. The last three years, our bay boat sales have been a third of what they used to be.”

A roadside sign seen in Stuart in late July. If you’re wondering what you can do about the ongoing crisis of Florida waters, we are called to consider our own water footprint, learn about the issues and get involved. And never forget that elections have consequences. Vote for Clean Water. (https://www.bullsugar.org/#)

What we have here in Florida is not just a crisis of water, we have a crisis of democracy and civic engagement.

From the beleaguered springs of North Florida to the sickened rivers and coasts of South Florida, we must understand that no savior is waiting on the horizon who will fix this thing for us.

It took a group effort to create this mess and we need all hands on deck if are to reclaim our waters. Florida needs environmental patriots willing to face down politicians funded by wealthy interests who think nothing of sacrificing our public waters on the altar of their private profits.

We don’t have the luxury of time to get this right. We are losing our waters now. This is our moment. It’s time to set aside our differences and focus on what is at stake, for this is nothing less than a battle for the soul of Florida.

The pictures don’t lie. We the people of Florida bear witness today to nothing less than a crime against nature, and a crime against the children who shall inherit our natural legacy.

A long time ago, Florida political leaders—Republicans and Democrats in common cause—understood there can be no healthy economy without a healthy environment. They wisely enacted laws and regulatory safeguards accordingly.

But that was then and this is now. It’s time to end the popular fiction in Florida that we can plunder and pollute our way to prosperity.

Gov. Reubin Askew said it best when he declared in 1971, “Ecological destruction is nothing less than economic suicide.”

In this, our Summer of Slime, can I get an amen?

NCCOS/NOAA Satellite Imagery, Making the Connection, Todd Thurlow

http://www.thurlowpa.com/LakeOImagery/NCCOS%20HAB%20Images/index.html

If you’re like me, you might wonder about the various satellite images in the news and on social media showing the cyanobacteria, also known as blue-green algae, in Lake Okeechobee. What’s the connection between the colorized and the not? How do the scientists determine the colorized image? Where do they come from?

In this post, I share a link to my brother, Todd Thurlow’s latest creation, “NCCOS HAB Images.” This exciting site juxtaposes an experimental product of the National Centers for Coastal Science, NCCOS, being used to track Harmful Algae Blooms, HABs, in Lake Okeechobee, to NOAA True Color, or enhanced traditional satellite images.
The NCCOS images are referenced by The South Florida Water Management District, however, experimental. Experimental or not they are cool, tell us a lot, and they are interesting!

Before relying on a CICyano (Chlorophyll Cyanobacteria Index) image, scientists must first look at the “true color” version to determine if clouds or sunlight reflections have corrupted the data. Todd has made it easy for us to compare the NCCOS “Chlorophyll Cyanobacteria Index” pictures to the corresponding “True Color” picture. He processed hundreds of images, putting them side by side. Generally, if there are clouds on the right image, then the left image may not be so reliable. But if there are no clouds on the right, then the left image is a good indicator of algae.

This site is an awesome visual tool we can now reference as we continue to learn about HABs in Lake Okeechobee. Technology is a powerful path for connecting to a “better water future.”

Blue-Green Algae Present, Lake O Bloom Subsiding, SLR/IRL

 

Documenting the discharges, is critical whether by air, on the ground, or from outer space.

The two videos above were taken by me over S-308 at Port Mayaca,  the opening from  Lake Okeechobee to the St Lucie River, and over S-80 at St Lucie Locks and Dam on Friday, July 20th, 2018. The satellite images below, my brother Todd Thurlow provided, were taken the same day.

It is clear that the blue-green algae/cyanobacteria, covering, at its height, 90% of Lake Okeechobee, has run its course and bloomed. Now, as the “flower falls,” we see what’s  left.

As seen in the aerials, and what the satellite images cannot portray, is that the algae is still there just lessened. Flying out over the lake a light green algae film remains over the water, a pastel shadow of its once flourescent self.

7-20-18, light colored algae, Lake O off eastern shoreline, JTL

The seven aerials at the end of this blog post were taken by my husband, Ed,  this afternoon, July 22, 2018 around 4pm. The tremendous green shock is gone, but squiggly lines of nutrient bubbles remain, and blue-green algae visibly lines the eastern shoreline to be sucked into the gates…

Will another gigantic bloom arise? Another flower to replace the dropped blooms of yesterday? Only time shall tell…

One thing is certain. Nutrient pollution (Phosphorus and Nitrogen) is destroying Florida’s waters, and unless non-point pollution, especially fertilizer runoff from the agriculture community, is addressed, faster than Florida’s Basin Management Action Plan requires- pushed out 30  or more years, we are will be living with reoccurring blooms indefinitely.

A great book on this subject is Clean Coastal Waters, Understanding and Reducing the Effects of Nutrient Pollution, National Reaseach Council 2000, https://www.nap.edu/catalog/9812/clean-coastal-waters-understanding-and-reducing-the-effects-of-nutrient

Read below how Florida is trying to fix its impaired waters; nice try but no urgency. As we all know, there is no time to wait.

Timely quote for thought by the late Mr Nathaniel Reed 1933-2018

“…The fact that the Department of Environmental Protection and the Everglades Foundation have at last identified every polluter in the vast Okeechobee headwaters is an astonishing feat. The sheer number of polluters is mind-boggling.

The failure to enforce the possibly unenforceable standard (best management practices) shines through the research as testament to the carelessness of our state governmental agencies about enforcing strict water quality standards within the watershed.

There is not a lake, river nor estuary in Florida that is not adversely impacted by agricultural pollution.

As one of the authors of the 1973 Clean Water Act, I attempted late in the process to include agricultural pollution in the bill, but the major congressional supporters of the pending bill felt that by adding controls on agricultural pollution the bill would fail.

Now, 54 years later, fertilizer and dairy wastes are the main contributors to the pollution of the waters of our nation. Algal blooms are all too common even on the Great Lakes.”

Lake Okeechobee Satellite Images 1982-2018, Todd Thurlow, SLR/IRL

 

In my last post, I shared my brother Todd Thurlow’s “Lake Okeechobee Satellite Images 1972-2013.” Today, I am sharing his Lake Okeechobee Satellite Images 1982-2018.

Hmmm?

In 1972, I was 8 years old…

In 1982, I was 18 years old…

A lot changes in ten years, and an extra-lot changes in the 100 years we have not taken good care of our state’s largest lake; this is now affecting millions of people and the remaining wildlife we have left.

Todd told me he did not “create by hand,” as I alluded to in my last post, but rather he used a USGS website tool to do it, and then converted, and loaded to YouTube, embed, etc.

In the last video the emphasis was on an a visible algae bloom in 1979, in this “video” the dates of algae blooms are not marked, but you can see clearly blooms towards the end as we reach 2018.

Unless something drastic occurs structurally, socially, and politically, I am sorry to say that we are doomed to have more and more algae blooms in the future.
